ATTACHMENT FOR, CHANGE-MAKING MACHINES.

Application led January 3,1916.

To all tf1/tom t may concern:

Be it known that I, FREDERICKk A. Nin- MANN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Attachments for Change-Making Machines, of which the following is a specification.

My invention relates to change making machines, and its object is to provide a novel device or attachment, the purpose of which is to replace, in their normal positions under the coin stacks, any coins which, through careless manipulation of the ejecting mechanism, have been displaced sufliciently to interfere with the subsequent operation of the machine. For example, in .a machine in which the coins are arranged in stacks and in which the ejecting slides operate against the lowermost coins in the stacks, the operator may not give a key its full stroke, in which case the coin will be only partially ejected, allowing the coins in the stack above it to take an oblique position in the coin holder, which prevents the ejecting slide, when reactuated, from com- -ing in contact with the partially ejected com.

My invention provides a simple attachment for a change making machine, by means of which the partially ejected coin may be replaced in the stack in line with the other coins thereof.

My invention is illustrated in connection with a change making machine of the type shown in my co-pending application Serial No. 39,991, filed July 15, 1915, but it will be obvious that the invention might be utilized in connection with other types of change makers. It will also be evident that the construction of the device might be varied somewhat from that shown and described herein without departure from the principles of my invention; although from the point oit view of simplicity, positiveness in its action and economy of manufacture, which are subordinate objects of my invention, I prefer to embody the invention in the construction substantially like that herein disclosed.

In the drawing: Figure 1 is a sectional View of a change making machine provided with the attachment of my invention, this view being taken on a plane indicated by line 1--1 of Fig. 2. Fig. 2 is a sectional Specification of Letters Patent.

plan view of the machine and attachment. Fig. 3 is a view, in perspective, of the coin replacing' member; and Fig. 4 is a similar view of the shaft for operating the same.

Like characters of reference indicate like parts in the several iigures of the drawing.

In the drawing, 10 indicates the casing of the machine which is formed with a plurality of coin pockets 11 Aadapted to hold stacks of coins. The pockets are ordinarily of different diameters accommodating the machine to coins of various denominations. As the ejecting mechanism forms no part of my present invention, it will not require description in detail. It will be suilicient to state that the lowei'inost coins of the stacks are ejected by a plurality of ejecting slides 12 which move in grooves 13 in a base plate l-i and are actuated in each case by a compound lever arrangement l5, 16, the lever 15 being provided with a nger-piece 17.

Fig'. 1 shows the lowermost coin c of one of the stacks partially ejected from, the stack with the coin above it tilted forwardly so that the coin o prevents the movement of slide 12.

The device for replacing the coin a to its normal position under the stack consists, in the preferred form shown in the drawing, of a coin replacing member 18 and a shaft 19 for operating the same. The coin replacing member 18 is pivoted within the casing 10 of the machine in the space back of the coin stacks. To this end it is formed Vwith gudgeons 2O which enter perforations 21 in the sidesv of the casing. The plate or member 18 is preferably made of sheet metal so that it may be sprung into place in the casing. It is normally held out of operative position and against a stop 22 by means of a spring 23 which is coiled around a lug 24 onsaid plate. The shaft 19 is revolubly supported in the casing and is formed with a crank 25 which bears against the rear side of plate 18. The shaft terminates in a lever 26 which lies outside of the casing, and is provided with a iinger piece 27. When the finger piece 27 is depressed the plate 18 is rocked so that it engages the partially ejected coin a and forces the same back under the stack.

In the change making machine shown the coin holders are of different diameter and arranged so that they are in line with each other at their forw'ard edges. This brings the rear edges of the holders out of alinement with each other and, to prevent coin holders of larger diameter from interfering with the complete replacement of the coins in the holders for the smaller coins, the plate 1S is formed with slits 28 and its lower edge bent to form tongues 29 which stand at different angles from each other corresponding to the deviation from alinement of the rear edges of the coin holders.

Operation: If the proper coin is not delivered from the machine the operator knows that the-ejecting mechanism was not given its full stroke, or this will be apparent if, on re-actuation of the ejecting mechanism in question the slide is locked against movement, as shown in Fig. 1. The operator, in such case, presses down the finger piece 27 of lever 26 and the coin replacing member is rocked forwardly so that its lower edge engages any coin or coins projecting backwardly from the stack or stacks and returns such coin or coins to the normal position. Spring 23 returns the coin replacing member andthe actuating shaft to their original positions.

I claim:

1. The combination witha change making machine comprising a coin holder for `holding coins in a stack and a coin ejecting mechanism; of a pivoted replacing member which is independent of said coin ejecting mechanism and which normally stands out of contact with the coin holder, and means for rocking the same into contact with a coin partially ejected from said stack so as to replace the same in its normal position.v

2. The combination with a change making machine comprising a casing provided with coin holders for holding coins in stacks Vand ejecting mechanism which operates to eject coins from said stacks; of a coin replacing member pivoted in said casing on the-other side of the coin holders from said ejecting mechanism, a spring to hold said member away from the coin stacks, and means comprising a lever located on the outside of the casing for rocking said replacing member against any coin partially ejected from one of said stacks to replace the same in normal position.

3. .The combination with a change making machine comprising a casing provided with coin-holders for holding coins in stacks and ejecting mechanism which operates to eject Vcoins from said stacks; of a coin replacing member pivoted in said casing on the other side of said coin holders from the ejecting mechanism, a spring to hold said member away from said coin stacks, and a shaft revolubly mounted in said casing provided with acrank which bears against said replacing member and with an operating lever on the outside of said casing.
